Optical characteristics of the Kara Sea derived from shipborne and satellite data

Results of optical studies of the Kara Sea waters are considered. The data of ship borne measurements are compared with satellite observations. The maximum values of the beam attenuation coefficient, the chlorophyll, and the yellow substance fluorescence were observed in the Ob gulf and in the coastal waters west of the Yamal Peninsula. The minimum values were observed in the central and western parts of the Kara Sea. Frontal zones with sharp changes of the parameters involved were observed. The distribution of the seawater’s optical characteristics was closely related to the hydrological structure of the Kara Sea’s waters. The data of the shipborne measurements were consistent with the satellite observations.
